How to Use a Mercury Sphygmomanometer [with Video]34

A mercury sphygmomanometer is a device used to measure blood pressure. It is the most accurate type of sphygmomanometer, and it is the type that is used in most hospitals and clinics. However, it is important to know how to use a mercury sphygmomanometer correctly in order to get an accurate reading.

Materials Needed* Mercury sphygmomanometer
* Stethoscope
* Pen and paper (optional)

Instructions1. Assemble the sphygmomanometer. The sphygmomanometer consists of an inflatable cuff, a mercury manometer, and a stethoscope. Connect the cuff to the manometer and the stethoscope to the cuff.
2. Position the patient. The patient should be seated with their arm resting on a table. The cuff should be placed on the patient's upper arm, about 1-2 inches above the elbow crease.
3. Inflate the cuff. Use the hand pump to inflate the cuff until the pressure reaches about 180 mmHg.
4. Listen for Korotkoff sounds. Place the stethoscope over the brachial artery, which is located on the inner side of the elbow. As you slowly release the air from the cuff, you will hear a series of sounds called Korotkoff sounds.
5. Record the blood pressure. The first Korotkoff sound is the systolic blood pressure. The last Korotkoff sound is the diastolic blood pressure. Record the two readings on a piece of paper.
6. Deflate the cuff. Slowly release the remaining air from the cuff.
